| 摘 要： | 龙永（龙山-永顺）高速公路选线设计中,在经过峡谷地段时采用高架桥还是隧道需进行方案比选。文中在分析了高架桥和隧道工程特点及现场地质构造等条件后,运用美国提出的交通与环境可持续设计发展理念——背景设计（CSD）,对两类方案从地质情况、施工难度、对环境的破坏等方面进行了分析比选,简述了背景设计理念在比选研究过程中的实践效果。

| Abstract: | In the period of Long-yong Expressway location design,it is necessary to determine the design scheme to be viaduct or tunnel when the route pass through the canyon. Analyzed the engineering characteristics of viaduct and tunnel and geological conditions, this paper select the two kinds of design scheme through some elements such as geological condition, construction difficulty, damage of environment with the sustainable design and development concepts on traffic and environment which comes from America called CSD. And then,it outlines the practice result of CSD in the selection process. |
